LOOlVl-SHUTTLE.

SPECIFICATION forming part of Letters Patent No. 394,915, dated December 18, 1888. 7 Application filed June 21, 1888. $erial No. 277,730. (No model.) v

To all whom it may concern.-

Be it known that I, SYDNEY S. EDwARDs, a citizen of the United States, residing at \Villiamstown, in the county of Berkshire and State of Massachusetts, have invented new and useful Improvements in Loom-Shuttles, of which the following is a specification.

In cop or loom shuttles having afiat spring to engage and hold the spindle-head a serious objection resides in the tact that the free end of the spring injures the paper tube, and also the yarn it the latter is wound low down or near the end of the tube, for the reason that the tube or the yarn comes into direct contact with the end of the spring whenever the cop is changed, thereby cutting the tube or the yarn, if the latter be wound low down,as stated. This will be obvious by stating that in shuttles of the character described the usual spinl'lle-head is pivoted and the extremity ot the tlat spring extends over and bears by its tlat under side directly upon such head sufficiently beyond the pivot ot' the latter to retain the spindle and cop in proper position within the shuttle. To apply a cop,

the spindle is turned on thepivoted head, the i latter riding under and forcing out the free end of the spring. The cop-tube is then forced down upon the spindle as tar as possible, and it the yarn is wound so low down as to cover the paper tube the yarn will be injured by forcible contact with the tree end of the spring, while it the tube be exposed the injury will be done to the tube itself.

The object of my invention is to avoid the objections stated without greatly increasing the cost of manulacturing the shuttles;and to such end the invention consists, essentially, in the combination, with a shuttle-bod y and a spimllehead, ot a spring-plate having ad jacent to its free end a depending lug, rib, or projection which bears upon the spindlc-head in such a manner that when the spindle is turned out ol' the shuttle the head, acting on the lug or rib, forces the free extremity of the spring-plate outward and holds such free extremity at such distance from the head that when the cop-tube forced down upon the spindle neither it nor the yarn will come into contact with the free extremity of the spring.

The invention also consists in the combina- 4 ing through an orifice, 8.

parts when the spindle is turned out of the shuttle-body and the cop forced thereupon, and Fig. t a detail perspective view looking at the under side of the spring-plate.

In order to enable those skilled in the art to make and use my invention, I will now describe the same in detail, reference being made to the drawings, wherein The numeral 1 indicates the body of acop or loom shuttle of any construction suitable for the purposes required; 2, the eccentricallypivoted spindle-head; 3, the paper tube, and 4 the cop. The shuttle-boi'ly is furnished with a recess, 5, containing the t] at spring-plate 6, detachably connected at its centc r to the shuttlebody through the medium of a screw, 7, pass- The spring-plate on its under side, over the spindle-head, is formed or otherwise provided with a depending lug, rib, or projection, (I, which bears upon the upper side of the head, and is here shown as a rib extending transversely across the plate at a distance from its extremity, so that when the parts are in the position. shown. in Fig. 3 such t'rec extremity will rest on the head beyond the pivot-point, being indicated by dotted lines, Figs. 2 and 3. The spring-plate is detachable, and the pressure exerted on the spindle-head can be varied by adjusting the screw. To apply a cop, the spindle is turned out and the paper tube is forced down upon the spindle, as shown in Fl 2; but as the spindle-head acts on the depending lug or rib 9 the free extremity of the spring-plate is held away from the spindle-head at such distance that the paper tube cannot come in contact with and be cut or otherwise injured by the free extremity of the spring; nor can the yarn be injured by the latter it wound down upon the tubeto cover the end portions thereof. 15y continued use the end of the springplate in action on. the spindle head will lose its tension or inherent elasticity, and to render the plate etiieient for av longer time I make said s n'ing-plate reversible and provide a lug or rib, J, near each end, so that when desired the plate can be reversed end for end, and this other lug brought into action. To aeeommodate the lug remote from the spindle-head, I provide the bottom wall of the cavity 5 with at reeess, 110, to receive said lug.

Having thus dcseribed my invention, what I claim is- 1. The combination, with a shutilc-bod and a spindle-head, of a spring having a lug to bear on the head and hold the free extremity of the plate from contaet with the cop-tube, subst aintially as described.

The combination, with a shuttle-lmdy and a pivoted spindle-head, of a spring-plate having on its under side a depending lug to bear on the head. and hold the free end of the plate from contact with the eop-tube when the spindle swung out oi the shuttle, substantially as described.

3. The combination, with a shuttle-body and a spindle-head, ot' a reversible sprine= plate having a ingadjacent to each end to bear on the head, substz'mtiallvas and I'orthe purpose described.

Intestimony whereof I ailix my signi-iture in presence of two witnesses.
